Local Environmental Conditions
A mix of eucalypt and wattle, wattle in particular a notorious trigger for hay fever across southern Australia, in the vicinity. This area, close by, has a park where mown turf grass and ornamental plane trees add to local grass and tree pollen. As with most local readings, actual levels can vary somewhat with short-term weather swings.
Eucalypt and wattle in the woods pick up where river oak leaves off, cresting around August and September in the year's sharpest tree-pollen spike. Grass pollen becomes the dominant allergen through spring, peaking in November, then persisting at a reduced but still meaningful level into the new year. The overall order of species tends to hold steady, even as exact dates shift slightly each year.

Does pollen in Glen Forrest come from nearby or far away?
Studies show that most pollen exposure (often 70–90%) comes from nearby sources, such as local trees and vegetation. A good pollen forecast therefore depends on accurately representing local vegetation. Pollen can travel long distances, but this usually matters only early in the season or during specific wind events.
Are pollen levels in Glen Forrest based on measurements or forecasts?
Pollen data is often misunderstood. Most "pollen levels" are not real-time measurements, but forecasts.
Direct pollen measurements are typically delayed by 1-2 days because they require manual analysis. To show current conditions in Glen Forrest, modern forecasts combine recent measurements, weather data, and information about local vegetation.
This allows us to estimate pollen levels for today and the coming days, not just report the past.

Understanding the Scale
The 0–100 scores represent risk levels, not direct measurements of pollen or air pollutant concentrations. Higher scores indicate higher risk. Pollen and air quality use different thresholds.
Pollen
| None | 0 | No or negligible risk of exposure. Pollen/mold exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen or mold spores may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen/mold exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen/mold exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen/mold exposure is expected to be at or near its highest levels. |
